Lost front wheel off my mountain bike - Myall Lakes - please help

I was riding a trail near Dark Point at Myall Lakes (just north of Stewart and Lloyd campground) off Mungo Brush Road on the 13th of April 2011. When I returned to my car, i took front wheel off to pack bike. I accidently left the front wheel and 15 mm skewer by the gate of the fire trail (LHS of the road as you drive north). It's the only front wheel I have for my Giant Trance X2, and I use the bike both recreationally, sometimes in enduro, and occasionly for a smooth commute. The rim is pretty standard and I think its a Maxis Cross Mark tread.

(realised about 200-250 Km later at a farm at about midnight and couldn't convince myself to drive back at the time (I've learned my lesson - "sorry mountain biking"...). Park Rangers reported seeing the wheel but assumed it had been left there so didn't pick it up (despite a message I'd passed on asking them to pick it up).

Any help appreciated (anyone know a friend in Tea Gardens / Hawks Nest who's found a MTB wheel lately??)
Cheers
Stew
